IMPROVEMENT IN WATER'METERS.'

Specification forming part of Letters Patent No. 148,073, dated March 3, 1874; application filed J anuary 21, 187 4.

To all whom 'it may concern:

Be it known that we, HARVEY REID LEON- AED and AMI PRINCE DENNrsoN, of the city of Portland, county of Multnomah and State of Oregon, have invented a new and useful Water-Meter; and we do hereby declare that the following specification is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, and made 'a part of this specification.

Figure l represents a longitudinal section of cylinder, showing inside of cylinder, with the stem B and collar on each end, marked X; also a plunger, marked a', which is grooved on the outer edge to form a water-packing. Letters K and K show a modified form of packing with leather, as at letters y y. The plunger in this case is made in two pieces, and bolted together at z z. A, Fig. l, shows an opening orl valve-seat, the bottom of which is perforated with port-holes d. d g g, forming the upper ends of the channels to the cylinder, (two on each end,) and are spaced, as is shown in Fig. 4. The ports or channels are lettered W W and V V-two on one side are for exhaust, and two on the opposite side are to receive the water. Figs. 5, 6, and letter O on Fig. 2, show the valve or cock, which has corresponding holes, to be arranged as on the drawing, Figs. 5, 6, and to be so iixed as to revolve backward and forward, opening the port d d on Figs. 4 and 5 and g g alternately, by the revolving motion of the arm L,lwhich is fastened to the stem B in Fig. 2, and is attached to the cock or valve at K K on Figs. 2 and 3. The arm is fastened to the stein by means of a set-screw or otherwise, and is arranged at the top end with a slot working on a pin, as at m m on Figs. 2 and 3. O is an arm, which revolves on the cock-stem 8, on which, as it moves backward and forward, it catches on a pin which is fast to the stem, as at Fig. 9. In the arm is a slot, at L L', producing a lost motion for the purpose of carrying the arm over the center with a ball or weight, not moving the stem until it drops over its center, and shifts the valve as the plunger moves backward and forward. By

the shifting of the valve the water is caused to enter first on one side and then the other of the plunger, and to be discharged through ports or channels arranged on opposite sides of the valve-seat and communicating through the same with the ports in the cock or valve. Fig. 10 shows the stufing-boxes for the stem in the cylinder and for the cock-stem.

The operation is as follows: Place the meter in a box level and properly fastened. After adjusting the cock-stem to the ports ina proper manner, so as to shift the water, as is already described, it is ready for operation. In order to prevent wear from the ball or weight dropping, a piece of wood should be placed across the box to catch the fall at a proper distance from the center on each side. Any kind of register, such as is usually employed upon gas-meters, can be attached to the machine on the end of the cock-stem at C. When the machine is adjusted and properly set the water enters in the ports at one end, moving the plunger to the opposite end, forcing it against the collar X, which .will force the cylinderstem out, moving the arm O' with the balanceweight over its center, at which point it will drop suddenly and shift the valve, causing the water to enter through the port at the opposite end, thus reversing the motion.

Our meter can be made of any kind of metal that is strong and will not corrode.

Having thus fully described our invention, we claim as new, and desire to secure by Letters Patentl. In combination with the channels W W V V and posts d d g g, the cock having the posts d d g g', substantially as described, and for the purposes set forth.

2. In combination with the stem B, having the collars X, arm L, and weighted arm O', the plunger a moving on the stein, all constructed and arranged to operate substantially as specified.
